Three types of masks dominate the Australian market. They perform differently. Here's the honest comparison.
Cloth masks
Do cloth masks filter PM2.5?
No, not meaningfully. Cloth masks — even well-made, multi-layered ones without a filter insert — have a filtration efficiency of approximately 10–30% for PM2.5-range particles. They block larger droplets and some coarser particles, but fine particles (bushfire smoke, most pollen, airborne pollution) pass through the fabric weave. A cloth mask without a filter insert is better than nothing for droplet protection; it is not a meaningful barrier against fine air pollution.
Best used for: casual everyday wear where filtration is less critical, or as an outer layer over a filter insert pocket.
Surgical masks
What does a surgical mask actually filter?
Surgical masks filter significantly better than cloth for particulates — the meltblown polypropylene middle layer is designed for filtration. Filtration efficiency with a good fit is approximately 60–80% for particles. However, surgical masks are designed for single use in clinical settings. They are not designed for multi-hour daily wear, their fit is loose with gaps at the sides, and the loose fit allows unfiltered air to enter around the edges. They also generate significant daily waste.
Best used for: short-duration clinical or healthcare settings where single-use, disposable protection is required.
Carbon filter masks (PM2.5 reusable masks)
Is a carbon filter mask better than a surgical mask?
For everyday use outside clinical settings — yes. A reusable mask with a fresh PM2.5 carbon filter provides filtration efficiency of 90%+ for PM2.5-range particles when fitted correctly. The carbon layer works via two mechanisms: mechanical filtration (physically trapping particles) and adsorption (the carbon surface chemically bonding to gases, VOCs, and fine particulates). This makes it effective against pollen, bushfire smoke, air pollution, and gases that surgical masks don't target at all.
Best used for: everyday protection against pollen, bushfire smoke, urban air pollution, long-wear comfort, and any situation where you want a practical, washable, reusable solution.
Side-by-side comparison
Cloth mask: PM2.5 filtration 10–30%, reusable (washable), no cost after purchase, not effective against fine pollution or pollen.
Surgical mask: PM2.5 filtration 60–80%, single-use (disposable), ongoing daily cost ~$1–2 each, good for short clinical use, poor long-wear comfort, significant waste.
Carbon filter mask (PM2.5 reusable): PM2.5 filtration 90%+, reusable outer + replaceable filters, moderate ongoing cost (~$5/week at 7-day replacement), effective against pollen, smoke, VOCs, gases. Best everyday option for Australian conditions.
Which type of face mask offers the best protection?
For the majority of everyday use cases — hay fever, commuting, bushfire smoke, flight travel, long-wear professional settings — a reusable mask with a fresh PM2.5 carbon filter offers the best combination of protection, comfort, and cost-effectiveness available without industrial-grade PPE.
For clinical environments requiring certified PPE, a certified P2/N95 respirator remains the standard. For all other everyday scenarios, a carbon filter reusable mask is the better choice.

Frequently asked questions
What is the difference between a cloth mask and a surgical mask?
A cloth mask is typically cotton or fabric with 10–30% PM2.5 filtration efficiency. A surgical mask uses a meltblown polypropylene layer with 60–80% filtration but is designed for single clinical use and generates significant waste. Neither filters as effectively as a reusable mask with a fresh PM2.5 carbon filter insert.
Is a carbon filter mask better than a surgical mask?
For everyday non-clinical use, yes. A reusable mask with a fresh PM2.5 carbon filter provides 90%+ filtration efficiency for PM2.5 particles, is more comfortable for long wear, reusable, and more cost-effective than daily disposable surgical masks. For clinical settings requiring certified PPE, a P2/N95 respirator is the appropriate standard.
Do cloth masks filter PM2.5?
No, not meaningfully. Cloth masks without a filter insert have approximately 10–30% filtration efficiency for PM2.5 particles — insufficient protection against bushfire smoke, fine pollen, or urban air pollution. A cloth mask with a PM2.5 carbon filter insert is a different product and performs significantly better.
Which type of face mask offers the best protection?
For everyday Australian use, a reusable cotton mask with a fresh PM2.5 carbon filter offers the best combination of protection, comfort, and cost-effectiveness. It filters 90%+ of PM2.5 particles, is comfortable for all-day wear, washable, and significantly less expensive than daily disposable masks.
What is a carbon filter mask used for?
A carbon filter mask (PM2.5 reusable mask) is used for everyday protection against fine air pollution, pollen, bushfire smoke, and gases. The carbon layer provides both mechanical filtration and adsorption of VOCs and odours. It's the best everyday mask choice for Australian conditions including hay fever season, bushfire smoke, and urban commuting.
